The survey of 600 likely Republican voters, conducted by Public Policy Polling (PPP), shows Romney having about 31 percent of the votes, compared to Newt Gingrich at 30 percent and Rick Santorum with 29 percent. Only 8 percent of those surveyed in Alabama said they've vote for Ron Paul. There is a four-point margin of error between the three leading candidates, according to the results released Monday morning.

When asked about how they liked each candidate, more people had a favorable view of Gingrich than they did of Romney.

"About all we know for sure about Tuesday's primaries is that Ron Paul will finish last in them," Dean Debnam, President of Public Policy Polling, said in a statement. "Beyond that it's plausible that any of the candidates could finish between first and third in both Alabama and Mississippi."

In addition to asking about the presidential race, the PPP poll also asked likely voters other questions. Here's a few examples:

--When asked whether President Barack Obama is a Christian or a Muslim, 45 percent of Alabama respondents picked Muslim, 14 percent said he's a Christian and 41 percent said they're not sure.

-- 21 percent of respondents they believed interracial marriage should be illegal and 67 percent said it should be allowed.

--In regards to evolution, 60 percent said they didn't believe in it, as opposed to 26 percent who did.

-- 67 percent of respondents said Alabama's immigration law is a good thing and 22 percent said it's bad for the state.

--When asked for their opinion of conservative commentator Rush Limbaugh, 53 percent said they had a favorable view of him and 33 said they didn't.

--Almost twice as many respondents said they're an Alabama fan over
Auburn. Fifty-eight percent said Alabama and 28 percent said Auburn.
